MOTORCRAFT GLOW PLUG SET (8)
fits All Ford 6.4L Powerstroke Diesel Engines
Causes of glow plug failure:

- Improper testing procedure (applying 12 volts directly to a glow plug designed to operate on 6 volts)
- Incorrect engine timing
- Improper fuel injector spray pattern
- Continual cycling of the glow plugs
